Huawei Solar SUN2000-50KTL-M3 solar inverter

Huawei Solar SUN2000-50KTL-M3

Built for commercial and industrial solar installations, this transformerless three-phase inverter delivers exceptional performance with its 50kW nominal power output and ability to handle peak loads up to 55kW. The unit achieves impressive efficiency ratings of 98.5% maximum and 98.0% European efficiency, ensuring minimal energy loss during conversion.

Four independent MPPT channels provide optimal power point tracking across diverse solar array configurations, with each channel supporting up to 30A DC input current and a wide voltage range from 200V to 1,000V. The robust IP66 protection rating ensures reliable operation in challenging outdoor environments, while the wide operating temperature range of -25°C to 60°C makes it suitable for various climatic conditions. At 49kg, this inverter combines substantial power handling capabilities with practical installation requirements.

Frequently asked questions

What size solar plant does the Huawei SUN2000-50KTL-M3 suit?

The Huawei SUN2000-50KTL-M3 delivers 50,000 W of nominal AC power and up to 55,000 W maximum, so it is a commercial three-phase machine for arrays in the tens of kilowatts rather than a domestic unit. The 55 kW ceiling gives installers headroom to oversize the DC array against the 50 kW nominal rating.

How many MPPT inputs does the Huawei SUN2000-50KTL-M3 have?

The Huawei SUN2000-50KTL-M3 has four MPPT channels, each accepting up to 30 A of DC input current. Four independent trackers let an installer split a commercial roof across differing orientations or tilts without one shaded section dragging down the rest, and the 30 A per channel is generous enough for two parallel strings of modern high-current modules.

How should strings be sized for the Huawei SUN2000-50KTL-M3?

The Huawei SUN2000-50KTL-M3 tracks from 200 V to 1,000 V and withstands 1,100 V of maximum DC input voltage. Strings must stay below 1,100 V at the coldest expected cell temperature and remain above 200 V when hot, a wide window that allows long strings and therefore fewer parallel runs across a large roof.

How efficient is the Huawei SUN2000-50KTL-M3?

The Huawei SUN2000-50KTL-M3 is rated at 98.5 percent maximum efficiency and 98.0 percent European efficiency. The European figure is the weighted one to use in yield calculations, since it accounts for the part-load hours that dominate a real year: roughly two percent of the array's DC energy is lost in conversion over the whole season.

What grid does the Huawei SUN2000-50KTL-M3 connect to?

The Huawei SUN2000-50KTL-M3 is a three-phase inverter listed for two alternative grid configurations, 400 Vac and 480 Vac, at either 50 Hz or 60 Hz, so the correct variant depends on the local network rather than being a single fixed rating. Total harmonic distortion is specified at 3 percent, clean enough for commercial grid-code compliance.

What does installing the Huawei SUN2000-50KTL-M3 involve?

At 49 kg the Huawei SUN2000-50KTL-M3 is a two-person lift and needs a wall or frame rated for that load. Its IP66 enclosure and declared operating range of -25 °C to 60 °C allow outdoor mounting in most climates, and the transformerless design keeps the mass down for a 50 kW machine.
